Resumen de: US20260048995A1
A method for manufacturing nano metal oxides and hydrogen includes the following steps: Step A, providing a first reactor, and placing a metal material, an alcohol compound, and a first catalyst in the first reactor and applying heating thereto for reacting to generate a metal alkoxide compound, while simultaneously generating a substantial amount of hydrogen; and Step B, providing a second reactor, and, after the metal material in the first reactor has fully reacted in Step A, transferring remaining solution in the first reactor into the second reactor, and adding a second catalyst and a controlled amount of water, and applying appropriate heating to generate nano metal oxide in powder form. As such, effects of significant reduction of production cost, enhancement of safety, widespread application of hydrogen fuel cells, extremely low carbon emissions, being defined as “green hydrogen”, and reduction of storage costs and risks can be achieved.
